A practical guide to cost optimization with Lakebase Postgres

Lakebase is a fully managed Postgres database designed for modern application development, featuring an architecture that separates storage and compute with a serverless compute layer. This design allows for cost efficiencies through various mechanisms: 1. **Branching**: Developers can create isolated environments for development, testing, or experimentation without duplicating storage costs, as branches share the same underlying storage. 2. **Autoscaling**: Lakebase adjusts compute resources based on activity levels, allowing users to pay only for the compute they use. It can scale down during low activity and can be suspended entirely after inactivity, reducing costs to zero. 3. **Read Replicas and High Availability**: The separation of storage and compute allows for adding read replicas and high availability without incurring additional storage costs, as these instances utilize the same storage layer. 4. **Synced Tables**: Integration with the Databricks Intelligence Platform enables efficient data syncing, allowing users to sync only the necessary working set of data, which helps avoid unnecessary storage and sync costs. 5. **Sync Modes**: There are three sync modes (Snapshot, Triggered, Continuous) for transferring data from the Lakehouse to Lakebase, each with different cost implications based on data freshness requirements. 6. **Right-sizing Compute**: Users can set the initial compute range during project provisioning to avoid over-provisioning and unnecessary costs. 7. **Monitoring and Metrics**: The Lakebase Metrics dashboard provides insights into working set size and cache utilization, helping users optimize their compute sizing and performance. 8. **Point-in-Time Restore (PITR) and Snapshots**: PITR maintains history for recovery within a configurable window, while snapshots offer discrete recovery points. Both are priced lower than standard storage, making them cost-effective options for data recovery. Lakebase costs are categorized into compute, storage, and serverless pipeline compute for syncing data. Compute is measured by CU usage, while storage includes branch storage, PITR history, and snapshot storage, all tracked separately. Users can access detailed usage and cost information through system billing tables.

We tested gaming performance in 17-year-old Windows 7 against Windows 11 on a modern gaming PC — older operating system delivers advantages in some scenarios

Windows 7 was released in 2009 and has received positive reviews for nearly two decades. A performance evaluation was conducted by installing Windows 7 on a modern PC and testing it against Windows 11 across ten games, including eight DirectX 11 titles and two DirectX 9 titles. In the game Metro 2033 Redux, Windows 11 achieved a higher average frame rate, but Windows 7 had better handling of CPU-related performance drops, resulting in stronger 1% lows. In Batman: Arkham Origins, Windows 7 outperformed Windows 11 in both average frame rate and 1% lows at 1080p and 4K. For Batman: Arkham Knight, Windows 7 showed higher performance when CPU-limited at 1080p, while Windows 11 led in GPU-limited scenarios at 1440p and 4K. In Batman: Arkham City, Windows 11 had the advantage across all resolutions as the game was GPU-bound. In The Witcher 3: Wild Hunt, Windows 7 outperformed Windows 11 in 1% lows at 1080p, but Windows 11 took the lead at higher resolutions. Control showed Windows 11 outperforming Windows 7 across all resolutions due to GPU optimizations. Hitman: Absolution also favored Windows 11 in GPU-limited scenarios. For DirectX 9 games, Windows 7 demonstrated significant advantages in average frame rate and 1% lows in Batman: Arkham Asylum, especially at lower resolutions, while performance in Borderlands 2 was nearly identical across both operating systems at 4K. Overall, Windows 7 excels in CPU-limited scenarios, while Windows 11 performs better in GPU-bound situations, aided by advanced graphics drivers. Microsoft’s ongoing efforts aim to improve Windows 11's performance and reliability.

Google redesigns the search bar in its Android app

Google has updated the search bar on the home screen of its Android app in version 17.65.17, introducing a new "plus" button for easier access to file uploads and AI tools. The redesigned search bar is slimmer with a white background, a border, and a shadow effect. The plus icon on the left allows users to attach images or files, create visuals with Nano Banana, or switch models in AI Mode, while the microphone and Google Lens icons remain on the right. The two shortcut buttons beneath the search bar now have text labels: "Create" for Nano Banana and "Talk" for Search Live, improving usability. The update is being rolled out broadly, but no specific timeline has been provided for when users in the UAE will receive it. Users need to update the app to version 17.65.17 to access the new search bar, and the plus button does not add new features but provides quicker access to existing ones.

How Telangana’s MeeSeva migration to open source could make governments rethink software costs

In April 2026, Telangana's MeeSeva platform migrated from the Oracle database to the open-source PostgreSQL database after 15 years of reliance on Oracle. This transition aimed to reduce annual costs of approximately ₹10 crore associated with Oracle licensing and maintenance. The initiative began in 2023, and the migration was executed with less than four hours of downtime, processing around 80,000 transactions daily. The migration involved over 85 microservices, three Oracle servers, and 1,939 tables, with the process automated by the Ora2Pg tool, which handled 60-70% of the transition. The migration cost was below ₹10 lakh, and after the switch, MeeSeva processed nearly 200 million transactions without data loss. The new architecture includes automatic failover capabilities to minimize disruption.
